The McGurk effect paradigm was used to examine the developmental onset of inter-language differences between Japanese and English in auditory-visual speech perception. Participants were asked to identify syllables in audiovisual (with congruent or discrepant auditory and visual components), audio-only, and video-only presentations at various signal-to-noise levels. In Experiment 1 with two groups of adults, native speakers of Japanese and native speakers of English, the results on both percent visually influenced responses and reaction time supported previous reports of a weaker visual influence for Japanese participants. In Experiment 2, an additional three age groups (6, 8, and 11 years) in each language group were tested. The results showed that the degree of visual influence was low and equivalent for Japanese and English language 6-year-olds, and increased over age for English language participants, especially between 6 and 8 years, but remained the same for Japanese participants. This may be related to the fact that English language adults and older children processed visual speech information relatively faster than auditory information whereas no such inter-modal differences were found in the Japanese participants' reaction times. 相似文献

This study quantified training load of various exercises using a novel method developed by the authors and based on the ratio of work completed: endurance limit, associated with exercise-induced delayed-onset muscle soreness. Exercises were also quantified using the Training Impulse method. 8 runners performed a marathon and a 60-min. run at marathon velocity, and 9 rowers performed two maximal exercises (500 m and 2000 m) on a rowing ergometer. To examine the validity of the two methods, the relationships between the training loads provided by the Training Impulse and the Authors' methods, the direct comparison of the tasks performed, and the usability of the Authors' method components in regular training were assessed. Authors' method was significantly related to Training Impulse method (r = .83, p < .05) and was higher for running (r = .94, p < .05) but none was observed for rowing. In both methods, the marathon run resulted in high training load compared with the other tasks. When compared with the 60-min. run, the training load of the 2000-m row was slightly higher for the Authors' method, but lower for Training Impulse method. In the Authors' method, the delayed-onset muscle soreness component discriminates the marathon from the other tasks whereas the ration of work completed: endurance limit differentiates the 60-min. run from the 2000-m row. The duration component of the Training Impulse method could lead to overestimation of the training load of prolonged exercises compared with high intensity exercise. The relationship between the Training Impulse and the Authors' methods for prolonged exercises, the training load provided for each task, and the components of the Authors' method supported the validity of this new tool to describe exercise-induced fatigue. 相似文献

Literature suggests that visuoperceptual deficits not normally assessed by eye examinations may be responsible for certain reading disabilities. Previous studies indicate that the use of nonoptical coloured filters may reduce these deficits and improve reading performance. Present research involved 49 participants with visuo-perceptual reading disabilities. Participants were divided into a control group who received no intervention, a placebo group who received filters in a colour complementary to the individual's optimal colour, and an experimental group who received specifically matched coloured filters. At posttest the experimental group reported statistically significantly fewer visual discomfort symptoms. The remainder of the results were, however, inconsistent. Some potential explanations are explored. 相似文献

In this paper I do two things: (1) I support the claim that there is still some confusion about just what the Quine-Putnam
indispensability argument is and the way it employs Quinean meta-ontology and (2) I try to dispel some of this confusion by presenting the argument in
a way which reveals its important meta-ontological features, and include these features explicitly as premises. As a means
to these ends, I compare Peter van Inwagen’s argument for the existence of properties with Putnam’s presentation of the indispensability
argument. Van Inwagen’s argument is a classic exercise in Quinean meta-ontology and yet he claims – despite his argument’s
conspicuous similarities to the Quine-Putnam argument – that his own has a substantially different form. I argue, however,
that there is no such difference between these two arguments even at a very high level of specificity; I show that there is
a detailed generic indispensability argument that captures the single form of both. The arguments are identical in every way
except for the kind of objects they argue for – an irrelevant difference for my purposes. Furthermore, Putnam’s and van Inwagen’s
presentations make an assumption that is often mistakenly taken to be an important feature of the Quine-Putnam argument. Yet
this assumption is only the implicit backdrop against which the argument is typically presented. This last point is brought
into sharper relief by the fact that van Inwagen’s list of the four nominalistic responses to his argument is too short. His
list is missing an important – and historically popular – fifth option.

The purpose of the present study was to examine whether intentionality of alcohol or club drug use would affect observer attributions
of a victim and a perpetrator after a sexual assault. Participants were 198 male and female college students sampled from
a small college located in the United States. In general, participants attributed less blame to the victim, more guilt to
the perpetrator, and were more likely to define the assault as rape and convict the perpetrator when the substance use was
involuntary as opposed to voluntary. Participants also attributed more blame to the victim and less pleasure to the perpetrator
when the sexual assault involved GHB as opposed to Everclear. Implications of these findings are discussed. 相似文献
